Applescript use google chrome to extract text

问题

I'm extracting text from a page on safari, everything work fine, However I can't adapt this script to Google Chrome

Here is the Safari code

to getInputByClass2(theClass, num) 
    tell application "Safari" 
        set input to do JavaScript "
document.getElementsByClassName('" & theClass & "')[" & num & "].innerHTML;" in document 1 
    end tell
    return input 
end getInputByClass2

Here is the Chrome code

 to getInputByClass2(theClass, num) 
    tell application "Google Chrome" 
        set input to do JavaScript "
document.getElementsByClassName('" & theClass & "')[" & num & "].innerHTML;" in document 1 
    end tell
    return input 
end getInputByClass2

have error "Expected end of line but found identifier."

回答1:

The command and the syntax for "Google Chrome" is not the same.

You must use the execute javascript command instead of do javascript.

And you must specify a tab from a window instead of in document 1.

tell application "Google Chrome"
    tell active tab of window 1 to set input to execute javascript "document.getElementsByClassName('" & theClass & "')[" & num & "].innerHTML;"
end tell
